Evocative, enigmatic, and haunted by airborne polyps, The Book of Ants, aka Livre des Fourmis, gives Trail of Cthulhu Keepers and players an essential window into Paris of the 20s and 30s, and into the Dreamlands beyond.

From November 1918 to September 1929, the young poet Henri Salem fell in with the surrealists of Paris. Swept up by the imperious charisma of group leader André Breton, he rapidly found himself sharing cafe tables with the key figures of this most influential and fractious art movement of the pre-war period. According to this, his diary of the era, he traded quips with Marcel Duchamp, feared the madness of Antonin Artaud, and served as model for the famous shot of ants crawling from a hole in a man’s hand in Salvador Dalí and Luis Buñuel’s scandalous film Un Chien Andalou.

If his tale can be fully believed, he stepped with them from waking Paris to an ancient yet surprisingly malleable realm of dream. (Save for Breton, who could never make the leap.) There he walked alongside such Mythos figures as Randolph Carter, King Kuranes and the ghoul once known as Richard Pickman.

As such his diary serves as an indispensable guide to anyone wishing to explore the dangerous demimonde of the Parisian art scene, where disagreements over aesthetics are often settled with knife wounds and broken bones. Even more, it provides a rare look into the ever-shifting shores of the Dreamlands, just as its air of the fantastical gives way to horrific reflections of a world spinning into chaos and death.
